Bei bekannten Kraftstoffexnspritzpumpen dieser Art ist nach Abschalten der elektrischen Anlage ein Wiederanlassen der Brennkraftmaschine nicht möglich, da das Magnetventil die Saugleitung sperrt.In known fuel injection pumps of this type, restarting is required after the electrical system has been switched off the internal combustion engine is not possible because the solenoid valve blocks the suction line.
Dies kann besonders unangenehm bei Schiffsmotoren sein oder in Fahrzeugmotoren, in denen längere Strecken in unbewohnten Gebieten zurückgelegt werden müssen.This can be particularly uncomfortable with marine engines or in vehicle engines where long distances in uninhabited areas have to be covered.
Der Erfindung liegt die Aufgabe zugrunde, eine Kraftstoffeinspritzpumpe zu entwickeln, die trotz Magnetventilsteuerung den Nachteil des Nichtwiederstartenkonnens nicht aufweist.The invention is based on the object of a fuel injection pump to develop which, despite solenoid valve control, does not have the disadvantage of not being able to restart.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß das Magnetventil im unerregten Zustand offen ist, so daß Kraftstoff aus dem Saugraum in den Pumpenarbeitsraum strömen kann. Die Magnetkraft wird hierbei durch die Druckdifferenz der Flüssigkeit von Saugraum zu Pumpenarbeitsraum bei der Betätigung des Magnetventilankers entgegen der Kraft einer Ventilfeder unterstützt.This object is achieved in that the Solenoid valve is open in the de-energized state, so that fuel can flow from the suction chamber into the pump working chamber. The magnetic force is created by the pressure difference of the liquid from the suction chamber to the pump working chamber during actuation of the solenoid valve armature supported against the force of a valve spring.
Ein Ausführungsbeispiel des Gegenstandes der Erfindung ist in der Zeichnung dargestellt und wird im folgenden näher besehrieben. Es zeigen:An embodiment of the subject invention is shown in the drawing and is described in more detail below. Show it:

Durch die Drehung der Antriebswelle 2 wird die Stirnnockenscheibe 3 und ein mit dieser durch ein Kupplungsteil 6 verbundener und auf die Nockenscheibe durch mindestens eine nicht dargestellte Feder gepreßter Pumpenkolben 7 in eine hin- und hergehende und gleichzeitig rotierende Bewegung versetzt. Die Zahl der Nocken 4 und damit die Hubzahl pro Umdrehung entspricht der zu versorgenden Zahl der Zylinder der Brennkraftmaschine. ·At the in Pig. Fuel injection pump shown 1 for multi-cylinder internal combustion engine is mounted in a housing 1 a drive shaft 2, to which an end cam disk 3 is coupled, which has a number of cams k, which cooperate with fixed rolls. 5 As a result of the rotation of the drive shaft 2, the end cam disk 3 and a pump piston 7 connected to it by a coupling part 6 and pressed onto the cam disk by at least one spring (not shown) are set in a reciprocating and simultaneously rotating movement. The number of cams 4 and thus the number of strokes per revolution corresponds to the number of cylinders of the internal combustion engine to be supplied. ·
Der Pumpenkolben 7 arbeitet in einer in das Gehäuse 1 eingesetzten, oben durch einen Ventilträger 8 verschlossenen Zylinderbüchse 9 mit Zylinderbohrung 10 und schließt dort einen .Arbeitsraum 11'ein. Vom Arbeitsraum 11 führt eine, im Ventilträger 8 angeordnete axiale Bohrung 12 in einen Sackraum 13, der über eine Leitung 14 eine Verbindung zur Bohrung 10 in der Zylinderbüchse 9 hat. Die Axialbohrung 12 ist durch ein in Richtung Arbeitsraum 11 von einer Feder 15 belastetes Ventilglied 16 verschließbar. Die Verbindungsleitung 14 mündet radial in die Zylinderbohrung"-10 und wird von hier aus über eine am Umfang des Pumpenkolbens angeordnete Ringnut 17 und einer mit dieser verbundenen Längsnut 18 entsprechend der Drehbewegung des Pumpenkolbens nacheinander bei jedem Druckhub mit einzelnen in die Bohrung 10"mündenden und zu den Zylindern der nicht dargestellten Brennkraftmaschine führenden Druckleitungen 20 verbunden. Die Druckleitungen 20 sind entsprechend der Zahl der zu versorgenden Motorzylinder gleichmäßig um die Bohrung 10 verteilt angeordnet.The pump piston 7 works in an inserted into the housing 1, cylinder liner 9 with cylinder bore 10 closed at the top by a valve carrier 8 and closes a workroom 11 there. From the work area 11 leads a, arranged in the valve support 8 axial bore 12 in a blind space 13, which is connected via a line 14 to Bore 10 in the cylinder liner 9 has. The axial bore 12 is through a in the direction of the working chamber 11 of a Spring 15 loaded valve member 16 closable. The connecting line 14 opens radially into the cylinder bore ″ -10 and is from here via an annular groove 17 arranged on the circumference of the pump piston and connected to it Longitudinal groove 18 according to the rotary movement of the pump piston one after the other with each pressure stroke with individual Pressure lines opening into the bore 10 ″ and leading to the cylinders of the internal combustion engine, not shown 20 connected. The pressure lines 20 are uniform in accordance with the number of engine cylinders to be supplied arranged distributed around the bore 10.
Bei jedem Druckhub des Pumpenkolbens 7 wird Kraftstoff über ,die Axialbohrung 12 unter öffnung des Ventilgliedes 16, den Raum 13, die Verbindungsleitung lh und dieWith each pressure stroke of the pump piston 7 fuel is over, the axial bore 12 with the opening of the valve member 16, the space 13, the connecting line lh and the

Verteilernut l8 zu einer der Druckleitungen .20 gefördert. Beim Saughub gelangt der Kraftstoff aus einem unter überdruck stehenden Pumpensaugraum 22 über eine Saugleitung 23, die in die Bohrung 10 mündet und einer von in gleicher Anzahl und Anordnung wie die Druckleitungen 20 an der Mantelfläche des Pumpenkolbens vorhandenen Längsnuten 24 in den Arbeitsraum 11.Beim Druckhub des Pumpenkolbens wird durch dessen Verdrehung die Verbindung zwischen der Saugleitung 23 und den Längsnuten 2k unterbrochen, so daß die volle vom Pumpenkolben geförderte Kraftstoffmenge einer der Druckleitungen 20 zugeführt werden kann. Außerdem ist die Saugleitung 23 durch ein Magnetventil 25 steuerbar, wie später näher ausgeführt wird.Distributor groove l8 to one of the pressure lines .20 promoted. During the suction stroke, the fuel arrives from a pump suction chamber 22 under overpressure via a suction line 23 which opens into the bore 10 and one of the same number and arrangement as the pressure lines 20 on the outer surface of the pump piston and into the working chamber 11 of the pump piston, the connection between the suction line 23 and the longitudinal grooves 2k is interrupted by its rotation, so that the full amount of fuel delivered by the pump piston can be fed to one of the pressure lines 20. In addition, the suction line 23 can be controlled by a solenoid valve 25, as will be explained in more detail later.
Zur Regelung der geförderten Kraftstoffmenge ist der Arbeitsraum 11 über eine axial im Pumpenkolben 7 verlaufende Sackbohrung 26 sowie eine die Sackbohrung 26 schneidende Querbohrung 27 mit dem Pumpensaugraum 22 verbindbar. Mit der Querbohrung 27 arbeitet ein Fördermengenregelglied 28 zusammen in Form eines auf dem Pumpenkolben verschiebbaren .Ringschiebers, der durch seine Stellung den Zeitpunkt bestimmt, an dem bei der Aufwärtsbewegung des Pumpenkolbens 7 die Querbohrung 27 geöffnet und eine Verbindung zwischen dem Arbeitsraum 11 und dem Pumpensaugraum 22 hergestellt wird. Von diesem Zeitpunkt an wird die Pumpenförderung in die Druckleitung 20 unterbrochen. Durch die Verstellung des Ringschiebers 28 kann somit die zur Einspritzung gelangende Kraftstoffmenge verändert werden.To regulate the amount of fuel delivered, the working chamber 11 is provided via a blind bore running axially in the pump piston 7 26 and a transverse bore 27 intersecting the blind bore 26 can be connected to the pump suction chamber 22. With the Transverse bore 27, a flow rate regulating member 28 works together in the form of a displaceable on the pump piston . Ring slide, which by its position determines the point in time when the pump piston moves upwards 7 the transverse bore 27 is opened and a connection is established between the working chamber 11 and the pump suction chamber 22 will. From this point in time on, the pump delivery into the pressure line 20 is interrupted. By adjusting the Ring slide 28 can thus reach the injection Fuel quantity can be changed.
Zur Kraftstoffeinspritzmengenänderung wird der Ringschieber 28 durch einen Reglerhebel 30, der mit einem Kugelkopf in eine Ausnehmung 32 des Ringschiebers 28 eingreift, verstellt. Der Reglerhebel ist dabei um eine Achse 34 schwenkbar, die durch einen Exzenter 35 einstellbar ist. Am anderen Ende des Reglerhebels 30 greift nicht dargestellt eine Regelfeder entgegen der Kraft eines.Drehzahlsignalgebers an. DieTo change the fuel injection quantity, the ring slide 28 is controlled by a regulator lever 30 which has a ball head engages in a recess 32 of the ring slide 28, adjusted. The control lever can be pivoted about an axis 34, which is adjustable by an eccentric 35.

Die Brennkraftmaschine wird durch Einschalten der Magnetspule 42 und damit Verschließen des Saugkanals 23 abgestellt. Nach Abstellen der die Brennkraftmaschine versorgenden elektrischen Anlage öffnet dann wieder das Magnetventil 25, so daß bei Wiederstart oder bei möglichem Ausfallen der elektrischen Anlage der Pumpenarbeitsraum 11 aus dem Saugraum- 22 mit Kraftstoff versorgt werden kann.The control spring is pretensioned by an adjusting lever changed, which can be adjusted arbitrarily. The speed sensor acts at increasing speed in the direction of reducing the amount to be injected while the spring acts in the direction of increase. The respective equilibrium position, which corresponds to a certain injection quantity., can be changed accordingly using the adjustment lever. The solenoid valve 25 is with its housing 37 in the Injection pump housing 1 screwed. The anchor 38 is' connected by a rod 36 to the movable valve part 40, which loads the suction channel by an opening spring 4l when the solenoid valve is switched off 23 releases. The facing sides of anchors 38 and core 39 are conical in order to generate a favorable magnetic flux per stroke when the magnetic coil 42 is excited to have. The internal combustion engine is switched off by switching on the magnetic coil 42 and thus closing the suction channel 23. After turning off the internal combustion engine supplying electrical system then opens the again Solenoid valve 25, so that the pump working space when restarting or in the event of a possible failure of the electrical system 11 can be supplied with fuel from the suction chamber 22.
